The embodiment of the invention provides a mobile terminal. The mobile terminal comprises a display screen, a main board and a photoelectric fingerprint identification module; the display screen comprises a lower substrate, a drive circuit board, a light-emitting device array, an insulating protective layer, an upper substrate and a light polarization plate, all of which are laminated in sequence; at least two groups of power interfaces are arranged on the main board; the drive circuit board comprises at least two drive circuit daughter boards; the daughter boards are connected with different power interfaces of the main board in an assembling manner; the photoelectric fingerprint identification module is arranged in the region which is at the lower side of the lower substrate and is dead against each drive circuit daughter board; and a power voltage of the drive circuit daughter circuit of the photoelectric fingerprint identification module, which is higher than that of the other drive circuit daughter board, is arranged at the lower side of the photoelectric fingerprint identification module. The mobile terminal provided by the embodiment can control brightened display of a partial region of a display screen.
